Answer:
<u>add up all numbers</u>
<u>then divide that number by the amount of numbers.</u>
Step-by-step explanation:
mad is basically finding the average of a set of numbers.
and how do you do that?
first, add up all numbers
ex: 1, 5,3,10,6,20,15,15,14 --> this adds up to 90.
then divide that number by the amount of numbers.
count how much numbers ehere are: there are 9 numbers.
divide 90 by 9 and the mad/average is 10.

Answer:
94 cm
Step-by-step explanation:
Set up and solve an equation of ratios:
wingspan length
60 meters 70.5 m
----------------- = ----------------
80 cm x
Cross multiplying:
(60 m)x = (70.5 m)(80 cm)
Solve for x by dividing both sides of this equation by 60 m:
x = (70.5 m)(80 cm) / (60 m) = 94 cm
The length of the model should be 94 cm.
Answer:
the area is 26 the perimetier is 52
Step-by-step explanation:
Answer:
1.) 90 ways
2.) 15,600 ways
3.) 24 ways
Step-by-step explanation:
1.) Let's say we are given 2 digits not equal to each other...The number of different orderings would be 2*1 = 2, or if we wanted the number of ways to order 2 digits chosen : 10*9 = 90 ways
2.) The number of ways to arrange 3 letters from 26 letters is:
26 Permutes 3 = 26! / (26 -3)! = 26*25*24 = 15,600 ways to choose 3 letters in a certain order
3.) 4 different chores. The number of ways to do them = 4*3*2 *1 = 24 ways
Multi-step equations are equations that require more than one step to solve.
For example:
2x+6 = 10 You subtract 6 from both sides
2x= 4 Divide both sides by 2
x=2 It took 2 steps to solve for x, so it is a muti-step equation.
One step equation:
2x =6 divide 2 by both sides
x=3 It only took one step, so it is an one-step equation.
